Adaption of Internal Load Capacity of i.MX 8QM Crystal Interface

we are trying to change the Load-Capacity for the 32kHz and the 24MHz crystals, which has to be done inside the i.MX 8QM.

How can we do so? We found BRD_OSC_CAP_TRIM_VALUE_24M and BRD_OSC_CAP_TRIM_VALUE_32K in the reference manual, but changing them in U-Boot is forbidden. Inside the firmware we can not find any settings.


I hope you can help us here,


Best regards,
